Capillin and capillen were effective in chlorophyllpreserving at concentrations of more than 10 or 25 μg · ml<sup>-1</sup> in the dark, and at 100 or 250 μg · ml<sup>-1</sup> the chlorophyll retention was about 80% of the initial value. However, capillen at 500 μg · ml<sup>-1</sup> was effective in chlorophyll-bleaching in the light. On the other hand, these compounds, at concentrations of less than 25 or 50 μg · ml<sup>-1</sup>, stimulated the loss of chlorophyll and completely eliminated the chlorophyll-preserving effect of kinetin in the dark. Capillarin was not effective in chlorophyll-preserving at any concentrations tested in the dark, but it stimulated the loss of chlorophyll and counteracted the chlorophyll-preserving effect of kinetin in the dark. From these results it is concluded that capillin, capillen and capillarin are essentially chlorophyll-degrading substances, and that chlorophyll-preserving activities of capillin and capillen at higher concentrations in the dark are due to their nonspecific and/or toxic effects rather than the inhibition of normal senescence.</p></div>","PeriodicalId":23797,"journal":{"name":"Zeitschrift für Pflanzenphysiologie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1984-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S0044-328X(84)80001-X","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82742769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
